Lt. Colonel Glenn Manning (Glenn Langan) has been given orders to keep his men safe from a nuclear blast, but when a civilian glider crashes close to the area, he races out to save the day. He ends up getting blown up real good — one would argue exactly like Dr. Bruce Banner five years later — and has third-degree burns all over his body. Then, the bad news. The plutonium blast has caused his old cells to stop dying while the new ones multiply at an accelerated rate. That means that he’s growing ten feet a day and there’s no sign of it stopping.
Before long, his heart and brain can no longer support him and he’s running wild, decimating the olf Vegas strip and throwing giant syringes at scientists before taking a tumble off the Hoover Dam directly into next year’s War of the Colossal Beast.
Jim Nicholson of American International Pictures made this movie because The Incredible Shrinking Man was a success and he had the rights to Homer Eon Flint’s The Nth Man, which is about a man ten miles tall. Charles B. Griffith was hired for the script ad Roger Corman was brought on board to direct but soon dropped out. You know, if you’re going to make a movie with way too big or way too small people, get the man whose very name says BIG: Bert I. Gordon.
